MetalKeen manufactures custom shaft couplings for industrial machinery requiring accurate torque transmission, reliable shaft alignment, and long-term operational stability.
A shaft coupling connects two rotating shafts to transmit torque while accommodating assembly tolerances, vibration, and limited shaft misalignment. Depending on application requirements, couplings may be designed as rigid or flexible, with customized bores, keyways, splines, flanges, clamp hubs, or set-screw connections.
Our couplings are manufactured from carbon steel, alloy steel, stainless steel, aluminum, and other engineering materials using precision CNC turning, milling, drilling, grinding, and dynamic balancing where required. Every coupling is produced according to customer drawings or OEM specifications to ensure high concentricity, accurate fit, and reliable torque transmission.
MetalKeen supplies custom couplings for paper machinery, pumps, gearboxes, conveyors, mining equipment, industrial automation systems, compressors, and heavy-duty rotating equipment.
A shaft coupling is a mechanical component used to connect two rotating shafts and transmit torque from a driving shaft to a driven shaft. Depending on the application, a coupling may compensate for angular, radial, or axial misalignment while reducing vibration and protecting connected equipment from excessive loads.
Our custom couplings are widely used in:
Paper Machines
Pumps
Gearboxes
Electric Motors
Conveyor Systems
Mining Equipment
Compressors
Steel Plant Machinery
Industrial Automation Equipment
Packaging Machinery
